let us know how it works out for ya
Keny - I think what you show here is what he already tried - and he said it restored to a date that the computer was messed up - (if i read his post correctly)
if you want to completely wipe it out and you DO HAVE the restore CD that the computer came with (i wasn't able to get that from your OP) you simply put your restore cd in the drive and boot to the CD - and "start over" with a fresh install of windows - when you are finished, there is usually an accompanying CD/DVD that had all your applications on it so you can put those back too.
If it is an HP and you didn't create your restore CD/DVD as suggested when it was new, you will more than likely have to order the CD/DVDs from HP - at a cost of about $30 for 2 day shipping.
If it is a Gateway, you should have mulitiple CDs - one with the operating system, one with drivers and one with applications (however, these 2 CDs might be combined on to one depending on the model / age of the PC)
If it is an IBM / Lenovo, they usually come with multiple restore CDs like the gateway
Dell usually has both - restore CDs and a recovery partition - I have only restored with CDs and never used the recovery partition
I'm sure some of the other choices have restore partitions, however, I don't own anything but Dell so I can't help you with that
My first suggestion would be to go to the website of the manufacturer of your computer and search system restore and see what their specific directions are.
